13544-43-9, 6-(Trifluoromethyl)-1H-indole is a indole-building-block compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
13544-43-9, To a solution of 6-trifluoromethyl indole (1.33 g, 7.18 mmol) in DMSO (7 mL) was added portionwise potassium hydroxide (0.75 mL, 13.37 mmol). The resulting solution was stirred at room temperature for 15 minutes. To this was added methyl-2-bromo propionate (3.6 mL, 32.29 mmol) in a single portion. The reaction mixture was stirred at room temperature for 16 hrs. The solution was cooled to 0 C. and quenched with water (20 mL). The mixture was extracted with CH2Cl2 (50 mL). This solution was washed with a saturated solution of ammonium chloride (2¡Á20 mL), brine (200 mL), dried over sodium sulfate, filtered, and concentrated. Purification via silica gel chromatography using 15-40% CH2Cl2 in hexanes gave the methyl ester as a clear oil (0.89 g, 3.23 mmol, 45% yield). LC/MS (10%/99% CH3CN (0.035% TFA)/H2O (0.05% TFA), m/z: M+1 obs=272.0; tR=3.56 min. 1H NMR (400 MHz, CDCl3) delta 7.73 (d, J=8.3 Hz, 1H), 7.62 (s, 1H), 7.45 (d, J=3.3 Hz, 1H), 7.39 (d, J=8.4 Hz, 1H), 6.67 (d, J=3.2 Hz, 1H), 5.26-5.20 (m, 1H), 3.76 (s, 3H), 1.88 (d, J=7.3 Hz, 3H).
The synthetic route of 13544-43-9 has been constantly updated, and we look forward to future research findings.
